摘要
针对清华大学10MW高温气冷堆模型进行MCNP程序的多群计算,多群数据库由DCL-75/BUGLE-80库经适当处理得到,使用离散角近似和等概率阶梯函数法逼近实际角分布。计算结果与二维SN程序DOT的计算结果进行了比较,两者较为一致。
Multigroup MCNP code calculation was made for the 10 MW High-Tempera- ture Gas-Cooled Reactor in Tsinghua University. Multigroup cross-sections were got from the DCL-75/BUGLE-80 cross-section library, using discrete angular representation and equally probable step function representation to approach real angular distribution. The results show that the multigroup MCNP and SN procedure DOT meet well.
